"Tracking the heat
The Vikings this year have new technology to help battle the heat and related illnesses. Vikings training staff are now able to wirelessly monitor players' body temperature while they practice. The players swallow a pill which contains a sensor that transmits a signal to staff telling them what the core temperature of the player is."
